Key Document


This reference design provides a compact and scalable camera module for automotive driver monitoring systems (DMS) and other vision applications. It combines a 2-megapixel (2 MP) imager with a 4-Gbps serializer and four-channel power management integrated circuit (PMIC).

The camera module is a two-board design to illustrate the flexibility and scalability of the power and serializer components to different image sensors, depending on the ADAS application. The 4-Gbps serializer incorporates FPD-Link III SerDes technology, enabling the transmission of uncompressed video data remotely to a display or machine vision processing system. Bidirectional control signals and power-over-coaxial (POC) can also be transmitted to the camera module with a single cable.

The camera PMIC enables a compact design optimized for flexibility and thermal performance by integrating three buck converters and one low-dropout regulator (LDO) with programmable output voltages and sequencing. Supervisors are integrated on each rail to further reduce the component count and overall form factor.

  • 20-mm × 20-mm power and serializer PCB compatible with a variety of image sensors
  • High efficiency and low noise power-supply
  • High-resolution camera applications with the 4-Gbps DS90UB953 device
  • 2.1-MP OV02311 imager from OmniVision™ providing full-HD, AD 10-bit, MIPI 2-lane, RAW10
  • Single Rosenberger FAKRA coaxial connector for digital video, power, control, and diagnostics
  • Additional diagnostic capabilities to enable ASIL
